And whats the purpose of the SCR is the SCR going to the batt or is it on the SGG side? Iam not as electronically smart as much as most of you. An SCR is basically a diode with a set voltage trigger right? So would that be placed just before the bulb to prevent any Voltage form reversing back to the cap. Iam looking at purchasing a 180000 uf 15V cap but not sure how to oscillate it with the neon bulb any help appreciated!  |
If that question was for me, anytime I discharged only a few volts above the battery, it was using 60v caps and each cap was 30,000uf. I had about 6 of them in parallel for about 180,000uf. The discharge for this setup was by mechanical pulley triggering a copper sheet switch that I made. This is the setup that allowed my charging batteries continue to charge/climb for up to an hour after there was no more input from the caps. This makes for a good strong charge.
The only time I used a neon bulb to discharge was on very, very low capacitance caps like 1uf, 0.1uf, 0.01uf and the caps were like 600volts. The voltages on this low of capacitance rose to the neon trigger voltage pretty easy. This setup was charging batts with too much radiant...not enough current to really get the batteries in true charging mode. The voltage climbs but it is really a fluffy electrostatic charge.
I never had capacitors get hot in either situation.
